Some embodiments of the present invention are described below with reference to fig. 1-4.
The utility model provides a multi-wing formula centrifugal fan, include: as shown in fig. 2, the volute 2 is provided with a first air inlet 21 and a first air outlet 22, as shown in fig. 1, the impeller 6 is arranged in the volute 2, as shown in fig. 3, the motor 4 is provided with a heat dissipation portion 43, and the heat dissipation portion 43 is in transmission connection with the motor 4; as shown in fig. 2, the bottom surface of the casing 1 is an open surface, the top surface of the casing 1 is provided with a second air outlet 12, the side surface of the casing 1 is provided with a second air inlet 11, a first heat dissipation port 101 and a second heat dissipation port (not labeled in the figure), and both the first heat dissipation port 101 and the second heat dissipation port (not labeled in the figure) are used for dissipating heat of the motor 4; the transmission mechanism is used for transmitting the power of the motor 4 to the impeller 6; as shown in fig. 1 and 2, the scroll casing 2 and the motor 4 are provided on the bottom plate 3; the bottom plate 3 is arranged on an opening surface of the casing 1, the volute 2 and the motor 4 are arranged in the casing 1, the second air outlet 12 of the casing 1 is connected with the first air outlet 22 of the volute 2, and the second air inlet 11 of the casing 1 is connected with the first air inlet 21 of the volute 2.
Specifically, the heat radiating portion 43 is provided in the motor 4 in a driving manner, so that the heat radiating effect of the motor 4 can be improved. The fan is used as the heat dissipation part 43, as shown in fig. 3, the fan is in transmission connection with the output shaft 41 of the motor 4, and can be realized through key connection, the motor 4 drives the fan to rotate, as shown in fig. 2, the housing 1 is provided with a first heat dissipation port 101 and a second heat dissipation port (not marked in the figure), and the air flow driven by the rotation of the fan enters through the first heat dissipation port 101 or the second heat dissipation port and goes out from the other heat dissipation port, so that the heat exchange efficiency between the inside of the housing 1 and the outside is improved, and the heat dissipation effect is improved.
Specifically, the motor 4 transmits power to the impeller 6 through the transmission mechanism, so that the multi-wing centrifugal fan can be prevented from generating heat and concentrating. The transmission mechanism can comprise a driving wheel 52, a driven wheel 51 and a transmission belt 5, wherein the driving wheel 52 is in transmission connection with the output shaft 41 of the motor 4, the driven wheel 51 is in transmission connection with the input shaft 61 through key connection, the transmission belt 5 is sleeved on the driving wheel 52 and the driven wheel 51 at the same time, and the power of the motor 4 is transmitted to the impeller 6. Because the heat of multi-wing formula centrifugal fan mainly comes from motor 4 and input shaft 61, so set up can part motor 4 and impeller 6's input shaft 61, avoid generating heat between them too concentrated, be unfavorable for the heat dissipation to avoid input shaft 61 ageing with higher speed, shorten multi-wing formula centrifugal fan's life-span.
Specifically, the motor 4 and the scroll casing 2 are disposed on the bottom plate 3, and the bottom plate 3 is disposed on the opening surface of the housing 1, thereby reducing noise. Because the motor 4 and the volute 2 are arranged in the shell 1, the noise generated by the vibration of the motor 4 and the interference of the volute 2 and the impeller 6 on the flowing air is partially absorbed by the shell 1 in the process of transmission, and the effect of reducing the noise is realized. So set up and also can avoid motor 4 to generate heat when too high, people mistake and touch the injured condition of motor 4, have also reduced motor 4 and spiral case 2 and have caused the condition of damage by external factor.
Specifically, the second air outlet 12 of the housing 1 is connected to the first air outlet 22 of the scroll casing 2, and the second air inlet 11 of the housing 1 is connected to the first air inlet 21 of the scroll casing 2.
It will be appreciated that the first and second air inlets 21 and 11 can enable the impeller 6 to suck and accelerate air, and leave the volute 2 through the first and second air outlets 22 and 12, so as to achieve ventilation effect. The first air inlet 21 and the second air inlet 11 are formed in the same shape, and the first air outlet 22 and the second air outlet 12 are formed in the same shape, so that the air exchange efficiency can be improved.
Further, a handle 14 is provided on the side of the housing 1.
It will be appreciated that the provision of handle 14 facilitates handling of the multiple-wing centrifugal fan, improving its portability.
Further, the first heat dissipation port 101 and the second heat dissipation port (not shown in the figure) are provided with dust covers.
It will be appreciated that the dust may affect the heat dissipation of the motor 4. The dust cover can reduce the entry of dust into the housing 1, thereby reducing the adhesion of dust within the housing 1.
